When estimating the value of Arabic numerals like ‘‘3,’’ ‘‘33,’’ and ‘‘333,’’ is each symbol treated holistically and associated with a different mental magnitude along a common scale (Dehaene, 1989), or is there unique scaling for units, decades, hundreds, and so on (McCloskey, 1992)? In this opinion piece, we argue that the evidence is more consistent with the holistic, single-scaling account...

The history of blood pressure (BP) waveform analysis is almost as undulatory as the waveform itself. The development of the sphygmograph in the mid-19th century led to a relatively brief, albeit intense, interest in the interpretation of the BP waveform. This was perhaps more an art than a science, and interest in the sphygmograph and the waveform declined after the introduction of the cuff-bas...

We measured spectral and time-domain properties of seismic events over a size range that spans magnitudes M r -2 to 8 in order to study earthquake source processes. In addition, we conducted laboratory experiments to study interseismic behaviors that can influence earthquake nucleation and we developed a model of eathquake rupture to explain the scaling behaviors we observe. To bridge the scale...

In [4], we have studied the statistical properties and mono-fractality of the power system time series, voltage magnitude (V), frequency (f), and phase angle (θ). The power system data was measured using three Phasor Measurement Units (PMUs) installed at Baylor University, Harris Substation, McDonald Observatory in the Texas Synchrophasor Network [1]. Our analysis of several data sets has shown...

We subjected the time series of quasi-rigid-body vibration pulses (elastic emissions) from laboratory fracture carried out by a piezoelectric accelerometer on concrete and rock specimens under uniaxial compression to statistical analysis. In both cases, we find that the waiting-time distribution can be described by a scaling law extending over several orders of magnitude. This law is indistingu...

Title of Document: A COMPARISON OF DIFFERENT METHODS THAT DEAL WITH CONSTRUCT SHIFT IN VALUE ADDED MODELING: IS VERTICAL SCALING NECESSARY? Yong Luo, Doctor of Philosophy, 2013 Directed By: Professor Hong Jiao Department of Human Development and Quantitative Methodology Construct shift is a term used to describe the change of tests in the construct they intend to measure. In tests across multip...

In designing the Hilbert transform pairs of biorthogonal wavelet bases, it has been shown that the requirements of the equalmagnitude responses and the half-sample phase offset on the lowpass filters are the necessary and sufficient condition. In this paper, the relationship between the phase offset and the vanishing moment difference of biorthogonal scaling filters is derived, which implies a ...

We used magnitude estimation to determine preferred datato-display mappings, polarities, and psychophysical scaling functions relating perceptual and conceptual data values to underlying acoustic parameters for blind and visually impaired listeners. We compare the resulting scaling functions to previous findings with sighted participants [1]. The findings have implications for the design of fut...

Weber's law can be explained either by a compressive scaling of sensory response with stimulus magnitude or by a proportional scaling of response variability. These two mechanisms can be distinguished by asking how quantities are added or subtracted. We trained Rhesus monkeys to associate 26 distinct symbols with 0-25 drops of reward, and then tested how they combine, or add, symbolically repre...
